These sit in different size classes, so this is not a straight ranking comparison. The JBL Partybox Stage 320 ranks #3 of 51 party speakers by sound quality at $499.95; the Sony ULT Tower 10 ranks #11 of 13 large party speakers by sound quality at $994.34.
The JBL Partybox Stage 320 is the battery-powered, lighter choice. An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. Its battery is rated for 18 hours, while the Sony ULT Tower 10 needs an outlet. At 36.4 lbs (16.5 kg) it weighs much less than the Sony ULT Tower 10 at 63.9 lbs (29 kg). It is rated IPX4, while the Sony ULT Tower 10 has no water resistance. Watch for: Slightly sibilant in the treble at full blast.
Why pick the Sony ULT Tower 10: A loud mains powered party tower with good sound and a wireless microphone included for karaoke. It supports LDAC Bluetooth, which the JBL Partybox Stage 320 lacks. The catch: Not as deep of bass and loses more bass at high volume even compared to the lower end Partybox speakers.
Buy the JBL Partybox Stage 320 at $499.95 if you want a party speaker. Buy the Sony ULT Tower 10 at $994.34 if you want a large party speaker instead.
